Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning brush, cleaning equipment and a cleaning system. Background Art

[0002] At present, the double-roller brush cleaning equipment on the market has a double air duct with a larger front and a smaller rear part on the floor brush part. During use, the suction force of the double air duct is dispersed, resulting in insufficient suction in the front air duct and incomplete cleaning. When the floor brush works backward, the rear air duct is easily blocked due to its small diameter and weak suction force, and water reflux is obvious. This forms a fatal flaw in the double-roller brush double-air duct cleaning equipment, which greatly affects the user experience.

[0003] For example, Chinese patent publication number CN217592737U discloses a cleaning device with an air duct and a floor scrubber equipped therewith. The airflow from the cleaning device travels from the front suction port through the front air duct to the converging air duct more quickly than the airflow from the rear suction port through the rear air duct to the converging air duct. Because the front roller brush serves as the primary cleaning brush and the rear roller brush as the secondary cleaning brush, the front air duct absorbs more material than the rear air duct. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a cleaning brush, a cleaning device and a cleaning system.

[0005] The embodiment of the present application adopts the following technical solution: a cleaning brush, comprising:

[0006] Housing assembly;

[0007] a first roller brush, which is arranged at the front end of the housing assembly and is capable of rolling contact with the ground;

[0008] a second roller brush, which is disposed at the rear end of the housing assembly and is capable of rolling contact with the ground;

[0009] a first air duct, one end of which is close to the first roller brush and communicates with the outside;

[0010] a second air duct, one end of which is close to the second roller brush and communicates with the outside;

[0011] a third air duct, one end of which is close to the other end of the first air duct and the other end of the second air duct, and the other end of the third air duct is connected to the main assembly of the cleaning device;

[0012] an air duct conversion member disposed at a junction of the first air duct, the second air duct, and the third air duct; when the cleaning brush moves forward, the air duct conversion member moves around a first direction to block the second air duct and connect the first air duct with the third air duct, thereby allowing dirt on the ground to enter the cleaning brush through the first air duct and the third air duct; when the cleaning brush moves backward, the air duct conversion member moves around a second direction to block the first air duct and connect the second air duct with the third air duct, thereby allowing dirt on the ground to enter the cleaning brush through the second air duct and the third air duct;

[0013] The first direction is opposite to the second direction.

[0014] When the local brush works forward, the air duct conversion part moves, connecting the first air duct and the third air duct in front and closing the second air duct at the back. When the local brush works backward, it connects the second air duct and the third air duct at the back and closes the first air duct in front. The air duct is switched by the movement of the air duct conversion part, thereby ensuring that a strong suction force of a single air duct is formed during the working process, and reducing the air duct switching time and the probability of clogging of the suction port, thereby solving the defects of the double roller brush in the existing technology, and completing a true double roller brush, a double air duct front and back suction cleaning system, reducing user usage restrictions, and greatly improving user experience.

[0015] In some embodiments, a first rotating shaft is provided at one end of the air duct conversion member, and a second rotating shaft is provided at the other end of the air duct conversion member; the middle part of the air duct conversion member is an arc-shaped plate, and there are sealing plates at both ends of the arc-shaped plate; when the air duct conversion member blocks the second air duct, the outer plate surface of the arc-shaped plate faces the second air duct; when the air duct conversion member blocks the first air duct, the outer plate surface of the arc-shaped plate faces the first air duct.

[0016] The blocking switching of the first air duct or the second air duct is achieved by the curved plate, and the switching process can be completed smoothly by the curved plate.

[0017] In some embodiments, a scraper is provided on the outer surface of the arc-shaped plate to reduce friction between the air duct conversion component and the outer shell component forming the first air duct or the second air duct when the air duct conversion component blocks the first air duct or the second air duct.

[0018] In some embodiments, the inner plate surface of the curved plate is a smooth curved surface. When the first air duct is connected to the third air duct, the smooth curved surface can smoothly connect the first air duct and the third air duct; when the second air duct is connected to the third air duct, the smooth curved surface can smoothly connect the second air duct and the third air duct.

[0019] The inner plate surface of the arc plate is a smooth arc surface, so that when the first air duct or the second air duct is connected to the third air duct, dirt is not easily accumulated at the connection between the first air duct or the second air duct and the third air duct.

[0020] In some embodiments, the first rotating shaft or the second rotating shaft is connected to the driving member, and a visualization window is also provided on the first rotating shaft or the second rotating shaft connected to the driving member for observing the connection status of the driving member and the first rotating shaft or the second rotating shaft.

[0022] The cleaning floor brush also includes a fixing seat, which is detachably arranged on the floor brush head. The fixing seat is hinged to the first rotating shaft and the second rotating shaft of the air duct conversion component so that the air duct conversion component can rotate relative to the fixing seat.

[0023] By arranging the air duct conversion component on the fixing seat, and the fixing seat being detachably arranged on the housing assembly, the air duct conversion component can be quickly disassembled.

[0024] In some embodiments, both the first rotating shaft and the second rotating shaft are provided with an annular protrusion around the axis of the first rotating shaft and the second rotating shaft;

[0025] Both ends of the fixing seat are provided with grooves respectively matched with the annular protrusions. The annular protrusions are placed in the grooves and rotate under the guidance of the grooves.

[0026] Through the cooperation of the annular protrusion and the groove, good positioning and guidance of the rotation of the air duct switching member can be achieved, so that the air duct conversion member can rotate stably to achieve the switching of the connection between the first air duct and the second air duct and the third air duct.

[0027] In some embodiments, a first soft scraping strip is provided at one end of the first air duct close to the first rolling brush; a second soft scraping strip is provided at one end of the second air duct close to the second rolling brush;

[0028] The first soft scraper strip and the second soft scraper strip are in contact with the ground.

[0029] The soft scraping strip is in contact with the ground and can scrape away water stains and garbage sucked in by the roller brush when cleaning the ground.

[0030] The present application also provides a cleaning device, including the cleaning brush described in any one of the above embodiments, and a main body component, wherein the main body component includes:

[0036] A body assembly, comprising a main board capable of controlling the movement direction of the air duct conversion member of the cleaning brush;

[0037] a handle assembly, which is arranged on the body assembly;

[0038] a sub-machine assembly, which is arranged on the main body assembly and is used to provide power and suction to the cleaning device;

[0039] a sewage tank assembly, which is arranged on the body assembly and is in communication with the third air duct of the cleaning brush, and is used to receive dirt from the third air duct;

[0040] A clean water tank assembly is arranged on the body assembly and is used to provide clean water for the cleaning equipment.

[0041] The embodiment of the present application further provides a cleaning system, comprising a base station and a cleaning device, wherein the base station comprises a blower and a hot air duct, wherein the hot air duct has a first hot air outlet and a second hot air outlet;

[0042] When the cleaning device is placed on the base station and is drying, the air duct conversion part of the cleaning brush moves to a preset position, and the fan and the sub-machine assembly provide suction so that the first air duct and the second air duct of the cleaning brush are connected to the third air duct, thereby enabling the fan to blow out the hot air through the first hot air outlet and the second hot air outlet, and blow the hot air to the first air duct, the second air duct and the third air duct of the cleaning brush through the hot air duct.

[0043] The beneficial effects of the embodiments of the present application are:

[0044] When the local brush works forward, the air duct conversion part moves, connecting the first air duct and the third air duct in front and closing the second air duct at the back. When the local brush works backward, it connects the second air duct and the third air duct at the back and closes the first air duct in front. The air duct is switched by the movement of the air duct conversion part, thereby ensuring that a strong suction force of a single air duct is formed during the working process, and reducing the air duct switching time and the probability of clogging of the suction port, thereby solving the defects of the double roller brush in the existing technology, and completing a true double roller brush, a double air duct front and back suction cleaning system, reducing user usage restrictions, and greatly improving user experience.

[0065] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0066] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but merely as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0067] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0068] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0069] It should also be understood that although the present application has been described with reference to certain specific examples, those skilled in the art will readily be able to implement many other equivalent forms of the present application.

[0070] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0071] Specific embodiments of the present application will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to variously utilize the present application with substantially any suitable detailed structure.

[0072] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0073] For cleaning equipment currently on the market with switchable suction ducts, the floor brush section of the cleaning equipment features a drive gear connected to an external gear. The outer wall of the cleaning equipment is rotatably connected to several support gears that mesh with the external gear, allowing the switching duct to rotate vertically to switch between the front and rear suction ducts. The complex transmission structure of the drive gear module significantly increases the cost of the product. Furthermore, the slow switching of the duct over long periods of use can easily lead to accumulation of waste in the suction port, causing the switching element to fail and cause varying degrees of blockage. This structure significantly reduces the life of the drive motor, reduces the cleaning performance of the product, and makes clearing blockage difficult, time-consuming, and labor-intensive.

[0074] The present application provides a cleaning brush 6, such as Figure 11 、 Figure 2 、 Figure 3 and Figure 4 As shown, the cleaning brush 6 includes a housing assembly, a first roller brush 7, a second roller brush 8, a first air duct 6.3.2, a second air duct 6.3.3, a third air duct 6.3.4 and an air duct conversion member 6.4.

[0075] The housing assembly serves as the installation base for other mounting structural components and provides installation space or installation locations for other structural components.

[0076] A first roller brush 7 is disposed at the front end of the housing assembly and is capable of rolling contact with the ground. A second roller brush 8 is disposed at the rear end of the housing assembly and is capable of rolling contact with the ground. The rolling of the first and second roller brushes 7 and 8 allows the cleaning of the ground at a location to be cleaned.

[0077] One end of the first air duct 6.3.2 is adjacent to the first roller brush 7 and communicates with the outside world. One end of the second air duct 6.3.3 is adjacent to the second roller brush 8 and communicates with the outside world. There is a certain gap between one end of the first air duct 6.3.2 and the first roller brush 7, and there is also a certain gap between one end of the second air duct 6.3.3 and the second roller brush 8, so that dirt on the ground can enter the first air duct 6.3.2 through the gap between the one end of the first air duct 6.3.2 and the first roller brush 7, and vice versa. Dirt on the ground can enter the second air duct 6.3.3 through the gap between the one end of the second air duct 6.3.3 and the second roller brush 8.

[0078] One end of the third air duct 6.3.4 is close to the other end of the first air duct 6.3.2 and the other end of the second air duct 6.3.3, and the other end of the third air duct 6.3.4 is connected to the main component of the cleaning equipment so that the dirt passing through the first air duct 6.3.2 or the second air duct 6.3.3 can enter the third air duct 6.3.4 and then enter the main component of the cleaning equipment for collection of the dirt.

[0079] The air duct conversion member 6.4 is located at the intersection of the first air duct 6.3.2, the second air duct 6.3.3, and the third air duct 6.3.4. When the cleaning brush 6 moves forward, the air duct conversion member 6.4 moves in a first direction to block the second air duct 6.3.3 and connect the first air duct 6.3.2 with the third air duct 6.3.4, thereby allowing dirt on the floor to enter the cleaning brush 6 through the first air duct 6.3.2 and the third air duct 6.3.4. When the cleaning brush 6 moves backward, the air duct conversion member 6.4 moves in a second direction to block the first air duct 6.3.2 and connect the second air duct 6.3.3 with the third air duct 6.3.4, thereby allowing dirt on the floor to enter the cleaning brush 6 through the second air duct 6.3.3 and the third air duct 6.3.4. The first direction is opposite to the second direction. That is, the air duct conversion member 6.4 can change its position according to the movement direction of the cleaning brush 6, so that the cleaning brush 6 maintains a single air duct operation, thereby ensuring the formation of a strong single air duct suction during operation, improving the utilization rate of the suction motor 2.5, and reducing the air duct conversion time and the probability of clogging of the suction port, thereby solving the defects of the double roller brush in the existing cleaning brush 6, realizing the dual roller brush and dual air ducts that can be switched back and forth to suction the dirt, greatly improving the user experience. Here, the single air duct refers to the air duct composed of the first air duct 6.3.2 and the third air duct 6.3.4 when the cleaning brush 6 moves forward; or refers to the air duct composed of the second air duct 6.3.3 and the third air duct 6.3.4 when the cleaning brush 6 moves backward.

[0080] It should be noted that forward movement refers to directions such as the front, left front, and right front, while backward movement refers to directions such as the rear, left rear, and right rear, rather than a single absolute front and back direction.

[0081] In the embodiment of the present application, when the cleaning floor brush 6 works forward, the air duct conversion part 6.4 is actuated to connect the first air duct 6.3.2 and the third air duct 6.3.4 in front and close the second air duct 6.3.3 at the back; when the floor brush works backward, it connects the second air duct 6.3.3 and the third air duct 6.3.4 at the back and closes the first air duct 6.3.2 in front. The switching of the air duct is achieved through the action of the air duct conversion part 6.4, thereby ensuring the formation of strong suction force of a single air duct during the working process, and reducing the air duct switching time and the probability of clogging of the suction port, thereby solving the defects of the double roller brush in the prior art, and completing the true double roller brush, and the double air ducts can be sucked forward and backward for cleaning, reducing user usage restrictions and greatly improving user experience.

[0082] In some embodiments, as Figure 8 、 Figure 9 and Figure 10As shown, a first rotating shaft 6.4.2 is provided at one end of the air duct conversion member 6.4, and a second rotating shaft 6.4.3 is provided at the other end of the air duct conversion member 6.4. The middle portion of the air duct conversion member 6.4 is a curved plate 6.4.1, and a blocking plate is provided at both ends of the curved plate 6.4.1. The blocking plates can block the ends of the curved plate 6.4.1. The first rotating shaft 6.4.2 and the second rotating shaft 6.4.3 can be respectively provided on the blocking plates at both ends of the curved plate 6.4.1. When the air duct conversion member 6.4 blocks the second air duct 6.3.3, the outer plate surface of the curved plate 6.4.1 faces the second air duct 6.3.3; when the air duct conversion member 6.4 blocks the first air duct 6.3.2, the outer plate surface of the curved plate 6.4.1 faces the first air duct 6.3.2. The blocking switch of the first air duct 6.3.2 or the second air duct 6.3.3 is realized by the curved plate 6.4.1, and the switching process can be completed smoothly by the curved plate 6.4.1.

[0083] In addition, a scraper 6.4.4 may be provided on the outer surface of the arc plate 6.4.1 to reduce friction between the air duct conversion member 6.4 and the outer shell component forming the first air duct 6.3.2 or the second air duct 6.3.3 when the air duct conversion member 6.4 blocks the first air duct 6.3.2 or the second air duct 6.3.3.

[0084] like Figure 3 and Figure 4 As shown, from the cross-section of the cleaning brush 6, the A duct conversion node of the arc plate 6.4.1 is connected to the lower part of the first duct 6.3.2, and the B duct conversion node is connected to the side of the third duct 6.3.4 close to the second duct 6.3.3. At this time, the horizontal position of the B duct conversion node is higher than the A duct conversion node, and at the same time, the C scraper 6.4.4 node moves to one side of the second duct 6.3.3 (to scrape the tiny particles in the first duct 6.3.2 to the second duct 6.3.3 and suck them away when moving in the second direction) and the first duct 6.3.2 is opened and the second duct 6.3.3 is closed to complete the cleaning during forward movement. When moving in the second direction, the B duct conversion node is connected to the lower part of the second duct 6.3.3, and the A duct conversion node is connected to the side of the third duct 6.3.4 close to the second duct 6.3.3. At this time, the horizontal position of the A duct conversion node is higher than the B duct conversion node, and the D scraper 6.4.4 node moves to the side of the first duct 6.3.2 (to scrape the tiny particles in the second duct 6.3.3 to the first duct 6.3.2 and suck them away when moving in the first direction). The second duct 6.3.3 is opened, and the first duct 6.3.2 is closed to complete the cleaning during the backward movement.

[0085] In some embodiments, the inner surface of the curved plate 6.4.1 is a smooth curved surface. When the first air duct 6.3.2 and the third air duct 6.3.4 are connected, the smooth curved surface can smoothly connect the first air duct 6.3.2 and the third air duct 6.3.4. When the second air duct 6.3.3 and the third air duct 6.3.4 are connected, the smooth curved surface can smoothly connect the second air duct 6.3.3 and the third air duct 6.3.4. The inner surface of the curved plate 6.4.1 is a smooth curved surface, so that when the first air duct 6.3.2 or the second air duct 6.3.3 and the third air duct 6.3.4 are connected, the connection between the first air duct 6.3.2 or the second air duct 6.3.3 and the third air duct 6.3.4 is not easy to accumulate dirt.

[0086] That is, the curvature of the curved surface formed by the inner plate surface of the curved plate 6.4.1 corresponds to the curvature formed by the inner cavities of the first air duct 6.3.2, the second air duct 6.3.3, and the third air duct 6.3.4, ensuring that the first air duct 6.3.2 and the second air duct 6.3.3 can smoothly transition the dirt and garbage at the air duct conversion part 6.4 after the air duct is changed. The outer curved surface structure of the curved plate 6.4.1 is provided with a scraper 6.4.4 structure to reduce friction during movement while ensuring sealing. This reduces the friction area of ​​the air duct conversion part 6.4, ensuring smooth movement and sealing of the air duct conversion part 6.4. At the same time, the scraper 6.4.4 is attached to the small particles remaining on the outer slide, which will be sucked clean during the next air duct change, effectively preventing blockage and achieving a better sealing effect when the first air duct 6.3.2 and the second air duct 6.3.3 are closed.

[0087] In some embodiments, as Figure 5 、 Figure 6 and Figure 7 As shown, the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 is connected to the driving member 6.5. A visualization window 6.4.5 is also provided on the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 connected to the driving member 6.5, which is used to observe the connection between the driving member 6.5 and the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3. The driving member 6.5 can be a motor, which can be a stepper motor capable of forward and reverse rotation. The visualization window 6.4.5 facilitates observation of the proper installation of the driving member 6.5 and also facilitates removal. The first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 has a built-in travel limit tooth 6.4.7 to control the movement of the air duct conversion member 6.4.

[0088] In some embodiments, the shell assembly includes an upper shell assembly 6.1, a lower shell assembly 6.2 and a floor brush head 6.3.1. The upper shell assembly 6.1 is arranged on the lower shell assembly 6.2, the lower shell assembly 6.2 is arranged on the floor brush head 6.3.1, and the floor brush head 6.3.1 serves as the main frame for installing the lower shell assembly 6.2 and the upper shell assembly 6.1.

[0089] The cleaning brush 6 also includes a fixing base 6.7, such as Figure 11 、 Figure 12 and Figure 13 As shown, the fixing base 6.7 is detachably mounted on the floor brush head 6.3.1. A sealing ring 6.8 is disposed between the fixing base 6.7 and the floor brush head 6.3.1 to prevent water leakage at this location. The fixing base 6.7 is hingedly connected to the first rotating shaft 6.4.2 and the second rotating shaft 6.4.3 of the air duct conversion member 6.4, allowing the air duct conversion member 6.4 to move relative to the fixing base 6.7. By mounting the air duct conversion member 6.4 on the fixing base 6.7 and detachably mounting the fixing base 6.7 on the housing assembly, the air duct conversion member 6.4 can be quickly disassembled.

[0090] In some embodiments, the first rotating shaft 6.4.2 and the second rotating shaft 6.4.3 are both provided with an annular protrusion 6.4.6 around the axis of the first rotating shaft 6.4.2 and the second rotating shaft 6.4.3, and the two ends of the fixed seat 6.7 are provided with grooves 6.7.1 respectively matching with the annular protrusion 6.4.6. The groove 6.7.1 can be a T-slot, and the annular protrusion 6.4.6 is placed in the groove 6.7.1 and moves under the guidance of the groove 6.7.1.

[0091] Mounting base 6.7 uses dual T-slots to secure duct converter 6.4. Duct converter 6.4 utilizes dual T-slot positioning and guidance, saving space while providing a strong seal during duct changes. The inner surface of mounting base 6.7 aligns with the outer curved surface of duct converter 6.4, ensuring smooth movement and minimizing the risk of particles entering the slide rails and affecting its operation.

[0108] When the floor scrubber is started by the switch on the button control panel 1.2 of the handle, the power is supplied by the sub-machine battery pack assembly 2.2, the suction motor 2.5 and the roller brush motor are started, the first roller brush 7 and the second roller brush 8 work at the same time, and when they move forward to clean, the main board 3.2 sends a signal to the driving member 6.5 of the air duct conversion member 6.4, and the driving member 6.5 moves a certain angle. Under the action of the driving member 6.5, the air duct conversion member 6.4 moves a certain angle, and the first air duct 6.3.2 is connected to the third air duct 6.3.4 and the second air duct 6.3.3 is closed at the same time. Under the clean cleaning, the dirt, sewage, garbage, etc. in the forward movement direction are cleaned and sucked away by the main suction force of the first air duct 6.3.2; when the floor washing equipment makes a cleaning movement backward, the main board 3.2 sends a signal to the driving part 6.5 of the air duct conversion part 6.4, the driving part 6.5 moves in the opposite direction for a certain angle, the second air duct 6.3.3 connects to the third air duct 6.3.4 and closes the first air duct 6.3.2 at the same time, under the clean cleaning of the second roller brush 8, the dirt, sewage, garbage, etc. in the second direction are cleaned and sucked away by the main suction force of the second air duct 6.3.3.

These plates converge toward one end of the first and second roller brushes 7 and 8, thereby increasing wind force and improving the drying effect. When the cleaning equipment is placed on the base station 9 and is dried, the air duct conversion part 6.4 of the cleaning brush 6 moves to the preset position, and the fan and the sub-machine component 2 provide suction so that the first air duct 6.3.2 and the second air duct 6.3.3 of the cleaning brush 6 are connected to the third air duct 6.3.4, so that the fan can blow out the hot air through the first hot air outlet 9.1 and the second hot air outlet 9.2, and blow it to the first air duct 6.3.2, the second air duct 6.3.3 and the third air duct 6.3.4 of the cleaning brush 6 through the hot air duct.

[0110] When the floor scrubber is placed on the base station 9 and self-cleaning is turned on by the handle switch, the main board 3.2 sends a signal to control the air duct conversion member 6.4 driving member 6.5, and the driving member 6.5 moves a certain angle. Under the action of the driving member 6.5, the air duct conversion member 6.4 moves a certain angle, and the first air duct 6.3.2 is connected to the third air duct 6.3.4 while the second air duct 6.3.3 remains closed. The main suction force of the first air duct 6.3.2 cleans up the dirt, sewage, particles, etc. remaining on the first roller brush 7. When the main board 3.2 sends a signal to control the air duct conversion part 6.4 driving part 6.5, the driving part 6.5 moves in the opposite direction for a certain angle. Under the action of the driving part 6.5, the air duct conversion part 6.4 moves in the opposite direction for a certain angle. The second air duct 6.3.3 is connected to the third air duct 6.3.4 while the first air duct 6.3.2 remains closed. The dirt, sewage, particles, etc. remaining on the second roller brush 8 are cleaned up by the main suction force of the second air duct 6.3.3. During the self-cleaning process, the air duct conversion part 6.4 is controlled by the program to circulate the air duct movement to complete the self-cleaning.

[0111] When the floor scrubbing equipment enters the drying mode on the base station 9, the main board 3.2 sends a signal to control the air duct conversion component 6.4 and the driving component 6.5. The driving component 6.5 moves a certain angle. Under the action of the driving component 6.5, the air duct switching component moves a certain angle, so that the A conversion node and the B conversion node are at a similar height. The first air duct 6.3.2 and the second air duct 6.3.3 are connected to the third air duct 6.3.4 at the same time, and the first fan 9.6 and the second fan 9.7 inside the base station 9 blow out hot air through the first hot air outlet 9.1 and the second hot air outlet 9.2 to form a co-flow circulation. The main force is the suction motor 2.5 of the fuselage, and the hot air fan of the base station 9 is auxiliary to suck away the water vapor formed by the residual moisture of the first roller brush 7 and the second roller brush 8, so as to achieve an efficient drying effect.
